This is probably more than adequate for daily online TV watching, actually. 
Perhaps not plentiful for HDTV, but enough for good Internet SDTV. Using 
Amazon, which tells me at what bit rate I'm streaming, I've seen up to 900 
Kb/s. Assuming an average 1 Mb/s (125,000 bytes/sec), 4 hours per day, 31 days 
per month, that still only adds up to 55.8 GBytes/month. And from what I've 
seen, they charge an extra $10 for each additional 50 GB, which is also not 
that bad. With your cap, HDTV 4 hours a day should also be feasible. Of course, 
that doesn't leave you much for anything else.

This shouldn't be a huge imposition for TV.

I think that's almost a separate issue. If it was network capacity during peak 
hours that were the problem, the solution would be different. Not a flat cap, 
but different rates, or different caps, for different times of day. The monthly 
cap is more or less of a blunt instrument, if your real goal is to prevent 
network saturation.

The network will saturate just as fast, caps or no caps, if everyone jumps on 
between 8 PM and 11 PM, let's say.

I wouldn't conclude that they're talking about IP delivery. We saw this coming 
a couple of years ago. At the time, IP wasn't mentioned as the technique, as 
far as I can remember. Whatever the case, it should leave more available 
bandwidth for IP broadband last mile links, anyway. Let's see if they put the 
extra capacity to work that way.
